Abstract
An electrical heater and a method of heating a catalyst. The heater includes a honeycomb body that includes a honeycomb structure. The honeycomb structure includes a central axis extending longitudinally and a plurality of interconnected walls. The interconnected walls include a plurality of radial walls extending along a radius of the honeycomb body between the central axis and an outermost periphery of the honeycomb body and a plurality of angular walls arranged concentrically with respect to the central axis and spanning between the radial walls. The honeycomb structure includes a plurality of cells defined by the interconnected walls. The heater comprises a first electrode disposed at the central axis and a second electrode disposed radially outwardly of the central axis and in electrical communication with the first electrode via one or more of the intersecting walls that are located between the first electrode and second electrode.
